VENTILATOR.

Specification of Letters Patent.

Patented June 1, 1920.

Application filed July 2, 1919. Serial No. 308,231.

To all whom it may concern:

Be it known that I, NIoHoLAs RENNER, a citizen of the United States, residing at Defiance, county of Defiance, and State of Ohio, have invented certain new and useful Improvements in Ventilators, of which the following is a specification.

This invention relates to a ventilating system which may be applied to houses or other buildings, and also to railway cars or ships.

The invention has for an object to provide a ventilating system which may be cheaply and easily installed during the construction of tne building, car or ship and which operates efliciently to constantly maintain a supply of pure air therein, and to avoid entrance of smoke, dust, cinders or the like.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claim in which the various novel features of the invention are more particularly set forth.

Figure l of the drawings is a longitudinal sectional view of a railway passenger car body having the invention embodied therein, this view being taken on the line '1.-1

of Fig. 4.

Fig. 2 is a similar view taken on line 2-2 of Fig. 4.

Fig. 3 is a horizontal section taken on the line 3+-3 of Fig. 4.

Fig. 4 is a transverse section through the car body, this view being on a larger scale than Figs. 1, 2, and 3.

Fig. 5 is an end view of the car body drawn to the same scale as Fig. 4.

Fig. 6 is a vertical sectional view of a building having the invention embodled therein.

Fig. 7 is a horizontal section on the line 7--7 of Fig. 6.

In Figs. 1 to 5 of the drawing, I have shown my improved ventilating system applied to a car of ordinary construction, the

doors, windows or other fittings being omitted since they have no relation to the present invention and illustration of such fittings is not necessary for a proper understanding of the invention.

, The car body here shown is of ordinary type with a floor 1, sides 2, ends 3 and roof 4:,the latter having the usual central raised portion 4'.

According to my invention the side portions of the roof are provided with longitudinally extending channels 5 and 6, the former being the inlet channel and the latter the outlet channel.

The inlet channel 5 communicates at its ends with the upper ends of vertical chan nels 7 and 8 in the end walls 3, the lower ends of these vertical channels being located near the floor and opening outwardly through the end walls. Screens 9 cover the entrance openings to these channels.

The outlet channel 6 opens directly at its ends through the end walls of the car as clearly shown in Figs. 2 and 3. These long'itudinal channels 5 and 6 communicate with the interior of the car through small openin s 10 and 1.1 respectively which are forme in the under walls of the channels and are spaced throughout the area thereof;

In operation of the ventilating system the fresh air enters through the screens 9 into the vertical channels 7 and horizontal channel 5 and flows through the openings 10 into theinterior of the car. The air afterward passes through the openings 11 into the channel 6 and out through the latter.

The inlet channel 5 is provided with a damper or shutter 15 at each end thereof, these shutters being opened or closed by means of rods 16 pivotally connected at their upper ends to the shutters and extending at their lower ends through spring clip brackets 17 of well known construction upon the end walls of the car by which the rods are held in adjusted position, the rods extending through suitable apertures in the inner wall of the channel 5.

As will be apparent the device can be easily regulated by the conductor by simply adjusting the rods or handles 16, the shutter at the forward end of the car being closed, and the shutter at the rear end being opened as much as desired to secure the proper ventilation, thus a constant supply of fresh air being insured while cinders, smoke, dust or the like are excluded.

In Figs. 6 and 7, I have shown my improved ventilating system applied to a building of ordinary construction having vertical walls 15 and 15, a ground floor'16, above which are the usual horizontal ceiling and flooring partitions 17. A vertical channel 18 extends upwardly in the wall 15 from a point near the ground floor 16, this channel having at its lower end an out- Wardly opening screened 'mouth 19.

A second-vertical channel 20 is formed in the wall 15 and extends upwardly from the lower ceiling and floor.partitions 17.

Formed in each of the partitions 17'are a pair of horizontal channels 21 and 22 which communicate by the branches 23 and 24 with the inlet and outlet channels 18 and 20 respectively. v

These horizontal channels 21 and 22 communicate with the rooms below them b meansof the small 0 enings 25 and 26 lea 'ing through the ceilings of the rooms into latter to the outside,'it being understood that inlet channel 18 is closed to the outerair at its upper end and outlet channel 20 opens to the outer air at its upper end.

It will be understood, of course, that the particular arrangement will carry according to the kind of building car, ship or other structure in which it maybe embodied, the invention being particularly suitable for application to schools, hospitals and like buildings. Where desired a filler of suitable construction can be applied to the intake opening to purify the air as it enters. It will be obvlous of course that shutters such as illustrated in Figs. 1 and 4 may be applied to the air inlet passages when the inventionisembodied in building? ships or any other structure.

aving thus described my invention what I claim as new and desire to secure by Letters Patent, is Y A railway car having a roof, a pair of parallel channels extending from end to end thereof, one of said channels opening directly through the'ends of the car, the end eral channels communicatin at their upper ends with the other 0 said parallel channels and at their lower ends with the exterior of the car, the car roofv being formed with passages leading from the in tGIiiOI' of the car to the said parallel channe s.
